In modeling what would be a rather difficult geometric structure, by using the High Level Generation tool in RISA-3D, a geodesic dome can be constructed rather quickly and easily.
- Select the High Level Generation button , and then select the Geodesic Dome option:
- The following dialog box will be displayed and you can enter in the necessary information for the geodesic dome generation:
Triangle Subdivision:Designate the number of triangle submesh per side of the triangular plate.
Geodesic Geometry Properties: Set the radius and dome height.
Geodesic Origin:Choose the dome origin coordinates.
Member:Check the Generate Members? box to create strut members. Designate the member prefix, a section set defined in your Section Sets spreadsheet, and the local x-axis rotation of the members.
Plates: Check the Generate Plates? box to create exterior plate members. Designate the plate prefix, a general material defined in your Materials spreadsheet, and the thickness of the elements
3. Click OK and the program will apply this information to create the geodesic dome structure.
